The primary energy use and emissions of housing sector in Taiwan

Abstract

Housing sector is one of the important greenhouse gases (GHGs) emissions which result global warming. In order to trace the energy use before and after primary energy factor of electricity adjustment, this paper analyzed the primary energy factor of electricity of the end user in Taiwan from 1982 to 2009 first. Then the compositions of the primary energy use and emissions in Taiwan housing sector were analyzed. The share of electricity use in total energy use of the housing sector was 64.2% at 2009 before primary energy factor of electricity adjustment. By using primary energy factor of the electricity demand of the year as adjustment, the share of the primary energy use of the electricity increased as 84.4%. Results of the research also showed that the annual log growth rate of the primary energy use induced by electricity use was 6.45% in Taiwan housing sector from 1982 to 2009. The total primary energy use of the housing sector in 2009 was about 5.7 times of which in 1982. Respect to emission factor of the housing sector, the research showed that the annual log growth rate of GHG Emissions of the housing sector was 7.81% from 1982 to 2009. The total GHG Emissions of the housing sector in 2009 was about 8.25 times of which in 1982. The shares of emissions from electricity in housing sector were 59.6% in 1982, and 86.6% in 2009. These results showed that the use of electricity was one of the major sources of the housing emissions growth this period.
